I am reading from the Australian Medical Council, Anthology of Medical Conditions (2003). Under the key objectives for presenting anaemia and pallor it says:
"By considering the clinical context, determine if anaemia is present, since all three laboratory indices of anaemia are concentration measurements." (p.91)
I am not a clinician, so to me this wording seems vague. In the first half it seems that clinicians may determine the presence of anaemia based on signs and symptoms elicited in the initial consultation, but in the second half it seems that clinical context includes the interpretation of bloodwork.
Can anyone clarify what is meant? Or instead tell me how one approaches anaemia?
